You need filters that fit the rack, arrive by the case, and don’t leave you guessing. Find your size below, then pick your grade: disposable panel filters for basic protection, MERV 8 pleated for everyday dust, or MERV 13 pleated when you need to catch finer particles.

Shop by type: Panel filters · Pleated filters · MERV 8 · MERV 13

Sizes are nominal. Check the size printed on the frame of the filter you’re replacing before you order. 1 in. and 2 in. filters come in cases of 12, and 4 in. MERV 13 filters come in cases of 6.

Who these are not for: these are HVAC-style replacement filters for air handlers and return grilles. We don’t sell HVAC equipment, and these aren’t dust collector filters. For cartridge, bag, and mist collector replacements, go to filters and consumables.
